Wi-Fi Modules:


Headquartered in Zhangjiang Hitech Park, Espressif Systems (Shanghai) Pte. Ltd. is a fabless semiconductor company providing cutting-edge low power Wi-Fi SoCs and wireless solutions for communications and IoT applications..

ESP8266 Based WiFi Modules:


ESP-WROOM-02D and ESP-WROOM-02U are ESP8266EX-based modules developed by Espressif. Compared to ESP-WROOM-02, the RF performance of ESP-WROOM-02D and ESP-WROOM-02U are optimized. Besides, ESP-WROOM-02U integrates a U.FL connector.

Certificates and Compliances:

  • Wi-Fi Alliance, SRRC, FCC, CE, TELEC, IC & KCC Certified
  • RoHS, Halogen Free, REACH & CFSI Compliant
  • Output Power: +22dBm peak power in FCC certification
  • Small Form Factor

    ESP8266 Module can be easily integrated into space-limited devices due to its small size of only 18mm x 20mm (ESP-WROOM-02) / 16 mm x 23 mm (ESP-WROOM-S2).


    2. ESP-WROOM-S2:

    The flash used on this module is a 2-MB SPI flash connected to HSPI, with a package size of SOP 8-150 mil. The gain of the on-board PCB antenna is 2 dBi. The ESP-WROOM-S2 works as the SDIO/SPI slave with the SPI speed of up to 8 Mbps.
